ABSTRACT:
The performance of a permselective cation transporting membrane is improved by making the membrane a three or more layer structure in which the layer having the best hydroxyl (OH) ion rejection characteristic is in the interior of the membrane. The OH ion rejection layer, which typically has sulfonamide or carboxylic functional groups, is covered by a cation transporting layer having sulfonate functional groups to which the cathode electrode is attached by bonding or otherwise. This keeps the high caustic concentrations present at the membrane-electrode interface away from the sulfonamide, etc. rejection layer.
